[Matplotlib-users] Interactive mode broken in Qt4Agg backend?

Hi,

I used to make animated figures generated with scripts similar to the 
one attached. It works fine with GTKAgg backend, but does not work with 
QT4Agg one: the figure just flashes at the end of the animation!

Is it a bug in Qt4Agg, or an unimplemented feature? Is there any way 
other than switching back to GTKAgg specifically?

Cheers,

Yannick

PS: I now about the recent Animation module, but I don't want to update 
all my scripts to this new framework.
